LUMBER-.WAGON.

SPECIFICATION forming part of Letters Patent No. 495,194, dated April 11, 1893.

Application filed November 14,1892- $erial No. 4:51.862. (No model.)

To all whom it may concern.-

Be it known that I, JOSEPH M. BLAKE, a, citizen of the United States, residing at Buffalo, in the county of Erie and State of New York, have invented certain new and useful Improvements in Lumber-Wagons; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use the same, referencebeinghadtotheaccompanyiugdrawings, and to figures of reference marked thereon, which form a part of this specification.

My invention relates to that class of lumber wagons which are so constructed and arranged that their loads can be dumped entire instead of being removed piece by piece and it consists of certain improvements in a form of lumber wagon for which Letters Pat-- ent N0.365,569 were granted to me on June 28, 1887. In such wagon friction rollers were provided resting upon the top face of and extending transversely across the sills and adapted to reciprocate thereon for the purpose of supporting the front end of the load while at rest and during its motion rearwardly, and one or more rollers mounted upon a shaft resting in bearings extending rearwardly beyond the sills with means for rotating such shaft and its rollers to move the load from off the wagon. To such a wagon I have added my improvements which consist first in providing adjustable means fortightening the endless chain employed in rotating the rollers at the rear end of the wagon frame; second, in improved spring bearings for the front and rear axles and the manner of securing them to the wagon body; and third, in other details of construction which will be fully set forth.

I will now proceed to minutely describe the manner in which I have carried out my invention, and then claim what I believe to be novel.

In the drawings, Figure 1 is a side elevation of the wagon complete. Fig. 2 is an enlarged top plan View of the rear end of the wagon frame broken away to show the tightening device. Fig. 3 is an enlarged side elevation of the rear axle bearings. Fig. 4 isa rear end View of the same. Fig. 5 is a perspective view of the two yoke blocks for the axle. Fig. 6 is a similar View of oneof the pedestals for the yoke blocks. Fig. 7 is a side elevation of the front of the wagon showing the front axle bearings, and Fig. 8 is a detached detail view.

Referring to the drawings, 1. 1 are the sills of the frame, and 2. 2. are friction rollers (see Fig. 8), connected in a frame 3, the rollers resting upon the top face of and extending transversely across the sills 1. 1. and adapted to reciprocate thereonfor the purpose of supporting the front of the load while at rest and during its movement rearwardly.

4 is a shaft mounted in the rearwardlyextending brackets 5. 5. on which are rigidly secured the rollers6 upon which the rear end of the load rests. At the outer end of the shaft 4 is keyed the large sprocket-wheel 7 around which passes the chain 8, and 9 is a small sprocket wheel around which the chain 8 also passes. The sprocket wheel 9 is mounted on the shaft 10 which also carries the double armed lever 11 for turning same, and 12 is a ratchet wheel, and 13 a dog for looking the shaft. chain 8 and two sprocket wheels 7 and 9 turn the rollers 6 to move the load rearwardly in dumping/the same; The parts thus far described are shown and claimed in my patent hereinbefore mentioned and form no specific part of my present invention.

As the chain 8 wears away from constant friction with the sprocket wheels it needs tightening and in order to provide for this I secure upon the under side of the sill and floor of the wagon the plate 13 upon the under side of which the shaft 10 is journaled. In this plate 13 are three elongated slots 14. 14. and 15 running lengthwise of the wagon and the plate is secured to the sill by bolts 16 passing through the slots 14.. 14 and to the floor proper through the slot 15 by the bolt 17. The elongated slots permit of a forward adjustment of the plate and with it its j ournaled shaft 10 and sprocket wheel 9 to the proper distance required to tighten up the chain 8 as it loosens through wear.

18 is the rear axle square in cross-section with the outer ends 19 for the reception of the wheels. The metal pedestals which form the casing carrying the yoke-blocks and spring are similar in configuration and each consist On turning the handle 11 the of the lower fiat body 20 having inwardly extending side flanges 21. 21, outer strengthening ribs 22 and outwardly projecting bottom lug 23. Its upper body 24 curves outwardly and inwardly on both sides having the upper wall or bearing plate 25, and 26. 26. are openings for the passage of securing bolts 27 to lock the two sections together. On the inner edges of the upper walls are the half-round notches 28 which when the pedestals are bolted together form circular openings, and 29. 29 are upwardly projecting lugs upon the outer edges of the bearing-plates 25.

30 is the upper and 31 the lower yoke block between which the axle 18 is secured by the bolts 32. The yoke block 30 has the halfsquare recess 33 upon its under side and the upwardly projecting extensions 34. 34. On either side and at each corner are the notches 35 extending from top to bottom.

A central top recess 36 receives the lower end of the spiral spring. The lower yokeblock 31 has the half square recess 36 upon its upper side which with the recess 33 in the yoke-block 30 forms when they are bolted together a square seat for the axle 18. Corner notches 37 in this block register with the notches 35 in the block 30. A brace 38 has secured to its rear end 39 by the rivet 40 the plate 41, having at each end the twoupwardly projecting lugs 42 and the end apertures 43.

The parts just described are assembled as follows: The pedestals 20. 24. are secured together by thebolts 27. 27 passing through the are in turn secured in position by the central bolt 44 passing through the lower wall of the bracket 5, the cross-piece 45 and the central orifice 28 in the joined pedestals. End bolts 46. 46 pass up through the end orifices 28 in the joined sections and through the crosspi'ece 45. The yoke-blocks 30 and 31 in which the axle 18 is securely bolted are then slid up between the lower ends 20 of the pedestals, the spiral spring 47 having been previously placed in position its lower end resting in the socket 36 in the yoke-block 30. The side flanges 21 restin the corner notches 35. 37. of the yoke-blocks. The plate 41 riveted at 40 to the brace 39 is brought under the lower ends of the united pedestals and secured together through the apertures 23 in the pedestals and the apertures 43 in the plate 41 and brace 39 by the connecting bolts 48, the lugs 42 upon the plate 41 resting against the outer sides 20 of the united pedestals. In this manner the yoke-blocks 30 and 31 carrying the axle have a vertical play within their casing against the action of the spiral spring 47, they being guided and controlled by the flanges 21 playing in the notches 35.37 of the yoke-blocks and the extensions 34. 34 upon the upper yoke block 30. The extensions 34. 34 present with the side walls of the yokeblocks on extended bearing against the inner faces of the pedestals 20 and reduces friction and consequently prevents undue wearing away of the surfaces in contact during vertical play. The pedestals being secured at three points, viz., 43. 43. and 40 to the brace 38 through the plates 41 together with the side-bearing of the lugs 42 upon the plate, it is practically impossible for a rupture or breakage to occur at this point of greatest strain.

The pedestals for the forward axle 18, (as shown in Fig. 8,), are similar in construction and arrangement to the rear pedestals, the brace 57 to which its lower end is secured extending up to the sills on both sides as. shown and there secured by bolts.

While I have shown my improved axle bear ings as applied to my particular dumping wagon for lumber, it is apparent that they can be applied equally Well to any other form of working wagon and I do not therefore wish to confine their use to this particular application.
